Kevalanvayi inference relies on a vyapti that is confirmed entirely through cases where both hetu and sadhya are present together, with no example of hetu existing without sadhya. The universality of the relation appears from the absence of counter-instances. This pattern is especially clear in cases where the hetu is coextensive with the broader class of the sadhya. Thus the inference in the stem is kevalanvayi.

Option A:
Option A, kevalavyatireki, is based solely on negative instances where both hetu and sadhya are absent together, and has no positive sapaksha examples, making it the opposite configuration.

Option B:
Option B, anvayavyatireki, uses both positive and negative instances and therefore does not restrict itself to only positive evidence.

Option C:
Option C is correct because kevalanvayi literally means "only by affirmative concomitance" and corresponds exactly to the case where there is no locus of hetu without sadhya. It highlights a particularly strong pattern of pervasion.

Option D:
Option D, samanyatodrsta, is a temporal and relational classification dealing with general uniformities rather than the specific structure of evidence for vyapti.
